[FFmpeg-user] Fwd: OBS and OBS Portable Recording Into Same File Simultaneously

[David Bayles]

I tried this:
C:\Users\David>ffmpeg -i "C:\Users\David\Downloads\2020-06-23 09-02-44
corrupt.mkv" -vf select='eq(pict_type\,I)'
"C:\Users\David\Downloads\2020-06-23 09-02-44 corrupt SELECT I-FRAMES.mkv"
2> "C:\Users\David\Downloads\2020-06-23 09-02-44 corrupt SELECT
I-FRAMES.txt"

And got this (video and log file):
https://drive.google.com/drive/folders/1OMf6oeLIkYU1d05dPqO1tfOxI1_KnYGK?usp=sharing

Is that what you meant to do? Any other ideas?

Thanks!
